-a virtual laboratory is not a physical segment in visual3d but is equivalent to a physical segment to the effect that it has a **segment coordinate system** that can be used to represent the laboratory (or other objects) and has an associated **surface model** that can be animated as part of the scene. a typical use of the virtual laboratory is to represent the floor so that motion capture markers can be projected onto the floor. this can be used for creating [[visual3d:documentation:pipeline:model_based_data_commands:joint_angle#joint_angle_normalization|normalized joint angles]].
